최신 Red Hat OpenShift EX380 무료샘플문제 (Q39-Q44):

질문 # 39
Kubeconfig Management - Use Context

정답：

설명：
See the solution below in Explanation:
Explanation:
Step 1: Make sure the context already exists in the kubeconfig file.
This follows the context creation Task SIMULATION .
Step 2: Run the command:
oc config use-context audit --kubeconfig audit.config
Step 3: Confirm the active context switches successfully.
The lab output shows:
Switched to context "audit".
Detailed explanation:
This command activates the audit context inside the specified kubeconfig file. Once selected, subsequent oc commands using that kubeconfig will default to the cluster, user, and namespace associated with that context.
This is operationally important because many administration mistakes come from running commands against the wrong cluster or project. Using explicit context switching reduces that risk and makes the kubeconfig usable for the intended audit workflow. In exams and real environments alike, the context is what turns separate kubeconfig elements into a working session configuration. Without switching to the correct context, even a well-formed kubeconfig may not be used as expected.


질문 # 40
Recover a NotReady worker node (basic remediation workflow)
Task Information : Diagnose a NotReady worker node and restore it to Ready state using standard OpenShift admin workflow.

정답：

설명：
See the solution below in Explanation:
Explanation:
* Identify failing node and status
* oc get nodes
* Confirms which node is NotReady.
* Inspect node conditions and events
* oc describe node < worker >
* Shows kubelet condition issues (network, disk pressure, runtime, etc.).
* Check MachineConfigPool state
* oc get mcp
* oc describe mcp worker
* If MCP is degraded, node may be stuck applying a config.
* Check node logs (kubelet)
* oc adm node-logs < worker > --path=kubelet.log
* Often reveals why node isn't reporting Ready.
* Remediate based on symptom
* Examples:
* If out of disk: free space, then verify kubelet recovers.
* If stuck MCO: investigate current/desired config and fix broken MachineConfig.
* If node cordoned/drained incorrectly: uncordon after remediation.
* oc adm uncordon < worker >
* Confirm node returns Ready
* oc get node < worker >


질문 # 41
Create and apply a MachineConfig (set MOTD on workers)
Task Information : Create a MachineConfig that writes /etc/motd on worker nodes.

정답：

설명：
See the solution below in Explanation:
Explanation:
* Create the MachineConfig YAML (example content encoded in base64)
* apiVersion: machineconfiguration.openshift.io/v1
* kind: MachineConfig
* metadata:
* name: 99-worker-motd
* labels:
* machineconfiguration.openshift.io/role: worker
* spec:
* config:
* ignition:
* version: 3.2.0
* storage:
* files:
* - path: /etc/motd
* mode: 0644
* contents:
* source: data:text/plain;charset=utf-8;base64,VGhpcyBpcyBhIHdvcmtlciBub2RlLg==
* MachineConfig uses Ignition format; file content is typically base64.
* Apply it
* oc apply -f 99-worker-motd.yaml
* Watch worker MachineConfigPool roll out
* oc get mcp worker
* MCP will show Updating then Updated.
* Validate on a worker node (if you have node access)
* Confirm /etc/motd contains the expected text.


질문 # 42
Prevent workloads from running on dedicated nodes (taints)
Task Information : Apply a taint to dedicated nodes so only pods with tolerations can run there.

정답：

설명：
See the solution below in Explanation:
Explanation:
* Taint nodes
* oc adm taint nodes worker-1 dedicated=payments:NoSchedule
* oc adm taint nodes worker-2 dedicated=payments:NoSchedule
* NoSchedule blocks new pods that do not tolerate the taint.
* Confirm taints
* oc describe node worker-1 | grep -i taints -A2
* Ensures taints are present.
* Validate effect
* A normal deployment without tolerations will remain Pending if it can only land on those tainted nodes.


질문 # 43
Create an Argo CD Application (OpenShift GitOps)
Task Information : Create an Argo CD Application that syncs from Git into namespace gitops-demo with automated sync enabled.

정답：

설명：
See the solution below in Explanation:
Explanation:
* Create target namespace
* oc new-project gitops-demo
* Destination must exist (unless Argo is configured to auto-create).
* Create Application manifest
* apiVersion: argoproj.io/v1alpha1
* kind: Application
* metadata:
* name: demo-app
* namespace: openshift-gitops
* spec:
* project: default
* source:
* repoURL: https://git.example.com/org/repo.git
* targetRevision: main
* path: manifests/demo
* destination:
* server: https://kubernetes.default.svc
* namespace: gitops-demo
* syncPolicy:
* automated:
* prune: true
* selfHeal: true
* automated: enables auto sync.
* prune: removes deleted objects from Git.
* selfHeal: corrects drift.
* Apply Application
* oc apply -f demo-app.yaml
* Verify sync health
* oc -n openshift-gitops get application demo-app -o yaml | grep -i -E "sync|health" -n
* oc -n gitops-demo get all
